Sibling to Oliver and Dexter

Hello,

Wondering if I could get some advice? Number 3 is coming in 3 weeks and, though we have a list, we're not super excited about any of them. It will be a sibling for OliverSkye (the Isle of Skye has some special meaning for us) and DexterJack (Jack is my late grandfather).

To complicate things a bit more we live in Quebec and the name should be fairly easy to pronounce in French - or at least the nickname.
